Fandoms can show their appreciation in a lot of ways: Tweets, fanmail, tattooing that person's face on their leg for all eternity. Recently, one of Floyd Mayweather biggest fans used up valuable real estate on his calf to do that last one, which is pretty good timing, considering his recent win against MMA fighter Conor McGregor.

Mayweather shared a photo of the tattoo, which features an incredibly life-like portrait of his face surrounded by money, with his Twitter followers saying, "I truly love & appreciate my fans. This tattoo artist is unbelievable."
